You run the ads, but the client owns the page. Ask for a designer brief and send it to the client the same day.

In-house marketer

PPC freelancer

Your ad numbers look bad when the page is weak. Audit the page before the first call and show the client what to fix.

Troubleshooting

If something goes wrong

Postclick's tools don't show up: Start a new chat. Most apps load a new connector when a chat starts.
ChatGPT answers without Postclick: Start your message with @Postclick.
No option to add a custom connector: Custom connectors depend on your Claude or ChatGPT plan. Check the plan in your account settings.
"Sign in again" or a sign-in error: Connect Postclick again. In Claude Code, type /mcp and pick postclick. In the apps, disconnect it and connect again.
Postclick can't find your page: Give the full page address, like https://example.com/landing-page.
The audit didn't start: It needs your yes. Postclick checks your plan and asks before any paid work, so reply yes to go ahead.
The audit is still running: Ask "how is my audit going?" The audit runs on Postclick, so you can leave the chat and come back.

FAQ

Questions about Postclick in ChatGPT

When will the ChatGPT plugin be live?

It's in review with OpenAI. Until then, the custom MCP server steps on this page give you the same 21 tools.

What is the Postclick MCP server?

It's a hosted MCP server that gives ChatGPT 21 landing page tools. You can read your Postclick audits, rewrite your page copy, check your ad against the page, see competitor ads and build a new page, all from the chat.

What is the server URL?

https://mcp.ppc.io. It's a remote server over Streamable HTTP with OAuth sign-in, so there's nothing to install.

Do I need an API key?

No. You sign in to Postclick in your browser the first time ChatGPT connects. ChatGPT gets a token and never sees your password.

Which AI tools does it work in?

Claude on the web, on desktop and in Claude Code, plus ChatGPT, Cursor, Grok, Windsurf, VS Code, Cline and Codex. Any app that can add a remote MCP server with OAuth can use it.

What does it cost?

Your first audit is free and needs no card. Starter is $70 a month for 10 audits and 2 new landing pages. Pro is $200 a month for 20 audits and 6 new pages.

Will it spend money without asking?

No. Only 3 tools use your plan: a new audit, page designs and a page build. Before any of them, ChatGPT checks what your plan covers, tells you and waits for your yes. If you asked for that audit or build in your message, that counts as your yes. Reading audits you already have is free.

Can Postclick change my live site?

No. You get the words to change, a brief for your designer, or a new page as one HTML file you own. In Cursor or Claude Code you can then ask the editor to make the change in your files, and you approve it there.

What's in an audit?

What to fix on the page, ranked, the doubts your buyers have, how well your ad matches the page, and the competitors bidding on the same searches.

Are my audits and pages private?

Yes. A draft stays private until you ask for a share link or publish it.

What does the free plan include?

One full audit of one page. Run it within 30 days of signing up.
